I didn't take note of all the stone drops, but I can assure you that my EM average is much higher than the HM one XDAnd now I don't even care since I already blessed everything that I needed.
What should I do with the extra stones? discard them?

EDIT: Is it possible that the Elyos version gives less stones than the Asmodian one? o.ò because I heard a lot of complains from Elyos, but not many from Asmos tbh

Well at the beginning of our NM tries, we tried to figured out how the Buff is working. And we noticed that most of the time, the one near the flower would get it, but not always. Same goes for 10min Freeze, nearer to the flower = higher possibility to get freezed.
